Frame Kit ZW1

The lightweight, super-efficient UHC Ultimate+Nano carbon fiber frame of the ZW1 frameset was designed with input from Felt's elite female road racers and triathletes. This isn’t just a repurposed men’s bike—the ZW1, built with Felt’s FitWoman geometry, is custom engineered to meet the specific needs of women athletes. Smaller-diameter carbon fiber tubes, a shorter cockpit to accommodate female proportions, and UHC Ultimate+Nano carbon fiber fork—it’s all part of the ZW1 package.

InsideOut is a revolutionary internally optimized molding process that completely eliminates excess material, and therefore weight, inside the frame tubes and junctions. Placing polyurethane inserts inside the frame during the molding process—especially at the bottom bracket and head tube area—and then applying a precise amount of pressure and heat results in perfectly formed tubes, inside and out.

Modular Monocoque Construction is an advanced carbon fiber manufacturing technique that allows Felt to mold individual sections of the frameset and then join them together. The main advantage of MMC is that it allows each section to be optimized to meet the specific engineering demands of that particular section of the frame.

UHC Ulimate+ Nano is the mark of Felt’s lightest, stiffest, best performing frames. UHC stands for Ultra Hybrid Carbon, and as the name indicates these frames feature a hybrid blend of high modulus raw carbon fiber. The stiffest fibers are used in certain areas of the frame, more durable fibers in others. Nano refers to a proprietary resin matrix that increases frame strength at the molecular level.
